The provided bar chart illustrates the expenditure patterns across different income brackets, namely low, medium, and high.
It is evident that housing expenses constitute just under one-third of the income for each demographic Additionally, low- and middle-income earners allocate approximately 19% of their budget to transportation, while the respective figure for their affluent counterparts stands at 15%. On the contrary, high earners are able to set aside 17% of their income for retirement planning, while the savings for the same purpose for the other two income groups differ by 7%, with their figures standing at 10% and 3%, respectively. All income groups exhibit the same spending behaviour when it comes to consuming food at home and paying for utilities. To be more precise, the most economically disadvantaged individuals pay more for both categories, with expenditures being represented equally at 12%. This is followed by the middle-income earners whose investments hover around 8%, while wealthy individuals dedicate merely 5% on average to this category. Lastly, it should be highlighted that the remaining categories (dining out, entertainment, clothing, health, and education) represent the least preferred choices to spend money on for all households. In particular, expenses fluctuate between 3% and 8%, with the highest proportion being recorded in health and the lowest in education for the low-income cohort.
On the whole, while insignificant variation can be observed in the spending behaviour of households, each income bracket primarily directs a substantial portion of their budget to housing.
